Slack's adapter registers a single parent slash command /hermes and dispatches subcommands via slack_subcommand_map(). Bare /sethome is not a registered command on Slack and fails with 'app did not respond', logging 'Unhandled request' in slack_bolt.AsyncApp. Show /hermes sethome in the first-run onboarding hint when the source platform is Slack; keep /sethome for Telegram, Discord, Matrix, Mattermost, and other platforms that register it directly.
